SEWING-MACHINE CABINET.

Original application led September To all ur/10m` t may concern:

Be it known that we,`EMIL A. KOPF and MARTIN HEMLEE, citizens of the United States, residing, respectively, at Newark, in the county of lssex and State of New Jersey, and at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Sewing-Machine Cabinets, of which the following is a specification, reference being had therein to the accompanying drawings.

rl`his invention has for an object to provide a sewing machine cabinet of simplified construction including means for manually driving and controlling the sewing machine; the parts of the cabinet being arranged so that they may be conveniently shifted or folded in such a manner, when not in use, as to inclose the sewing,r machine and practically conceal the same together with the various controllingr and driving devices therefor, whereby the complete outfit will have the neat and trim appearance of. and be adapted for use as, an ordinary table.

Further objects of the invention will appear from the followingr description and claim.

The invention, in its preferred embodiment, comprises a four-legged table, the top of which is apertured to the usual belt driven sewing head. Means are )rovided whereby the sewing head may be dropped or swung below the table-top; the latter` including end-leaves which may be folded. over to meet along.r the center line extending: transversely of the table-top. A treadlc is su i )orted near the floor within the space delihed bythe table-legs and is connected by a pitnlan toa drivewhecl journaled at the under side of a lower leaf or shelf member which is hinged at one end to a cross-piece carried by an end pair of lthe adapted to be swung from a horizontal position, concealing drivelwheel. to an upright said treadle and drivesubstantially said treadle and position ekposing wheel and positioning: the latter in operative relation to said treadle and to the driven pulley ol the sewing head with which Said drive-wheel mayv hc connected by means of the usual belt.`

and this application tiled August similar view with the parts folded into 4 1s a fragmentary rear elevation of the treadle-control mechanism showing the operative connection between the treadle and drivinglr pitman. Fig. 5 is a fragmentary plan view of the treadle. Fig. 6 is a perspective view of the retaining r vlatch for the treadle concealingr leaf or shelf and Fig. T is a sectional view showing the means for supporting,r one o1 the extension leaves of the table-top in the position shown in Fig. 1.

As disclosed in our copending application Serial No. 191,495, liled Sept. 14, 1917, of which this application is a division, the present cabinet, in its preferred embodiment, includes a table havinpr a table-top 1 supported at its four-corners by legs 2, the end pairs of which are connected by up er and lower end braces or cross-bars 3 an( 4, respectively, which support the spaced and vertically disposed end-slats 5.

The means incorporated in the cabinet for suplmrtiugr the sewingr head so that it may be swun, r or dropped from the position shown in Fig. El to a position below the level ol' the table-top are constructedsubstantially in accordance with the disclosure in the United States patent to Diehl et al.. No. 541.444: the rear side of the machine bedplate being supported by the usual hinged pins. one of which is shown at 6, and the front side of said bed-plate resting noon the lip T of the hinged leaf 8. lVhen 4the machine is to be dropped below the table-top 1 the hinged leaf 8 is first lifted to carry its lip 7 out of range of the front edge of the machine base. whereu )on the machine may be lowered in the usual manner into the yreceptz'xcle beneath the table-top. The usual counterhalancing: spring.;r 9 acts to partially support'the machine head. all as more fully described in tl," .said Diehl et a?. patent.

In the lnesent instance. the cabinet is equipped with any Suitable belt driven sewing head. Such a sewing head usually includes a bed 10 from which rises a Standard 11 carrying a bracket arm 12 within which is journaled a Inain-shaft 12', Fig. 3, upon the rearwardly projecting end of'which is secured the usual hand or balance-wheel 13 having a belt-gr0ove 14 for the driving belt 15.

Hinged to the opposite ends of the tableto 1 are the extension leaves 16, 16, the le t-hand one of which, Fig. 1, is supported in oien position by the rod 17 which is slida. ly received within thesheath 18 screwed to the under side of the table-top l, as shown in Fig. 7. Then the cabinet is closed, the extension leaves 16, 16 are folded over upon the table-top 1 and meet at the center of the latter to conceal the aperture for the sewing head and form a smooth flat top for the cabinet which then has the appearance of a simple table.

Secured to the cross-bars 4 are brackets 19 formed with socketed bosses 2() in which are tixedly secured the opposite ends of the round tie-rod'21 which supports the treadle 22; the latter being formed with the depending: apertured ears 23 entered by said tie-rod and held in position longitudinally of the latter by suitable collars 24.

Hinged to the ledge 25 which projects inwardly from the right hand cross-bar 4.- is the lower leaf or shelf member 26 on the inner side of which is rotatably mounted the grooved drive-wheel 2T carryingr a ball crank-pin 28 embraced by the socketed npper end of the pitman 29, the lower end of which carries a ball 30 embraced by the socketed extension piece 31 which is detachably secured to the treadle 22 by screws 32. As will be observed, the socket of the extension piece 31 which embraces the ball 30 is formed of two separable disks 33 and 34 secured together and to the extension 31 by screws 35; said disks beingv cut away at one side to afford a clearance space 36 permittin;r the pitman 29 to assume the down turned position illustrated in Fig. 2.

The leaf 2G is retained in upright or running position by means of the latch 37 mounted to turn upon the stud-pin 38 carried by the plate 39 screwed to the inner face of the right-hand cross-bar 3, Figs. 1 and 3. The latch 37 comprises a stop 4() adapted to arrest the upward and outward movement of the leaf 2G and a retainer projection 41 adapted to be turned so as to project below the upper edge of the leaf 2G when in upriglit.positio11, as shown in Fig. 1. lVhen the leaf 2G is lowered to closed or inoperative position, Fig. 2, the treadle and drive-wheel are substantially concealed from view; the balland-socket connections at the opposite ends of the pitman 29 permit-ting closure of the leaf 26 without disconnection of said pitman from the treadle and drivin wheel.

he cabinet is provided with suitable drawers for accessories and attachments. The large center drawer 42 is hinged at 43 to swing outwardly and dmvnwardly to open position. while the smaller end drawers 44 are slidably mounted in the usual manner.

The specific embodiment of the invention shown and described is not intended to limit the scope of the appended claim as it will be apparent to those skilled in the art that the described construction is susceptible of material modification both in the form and arrangement of the various parts within the spirit of the invention.

Havingr thus set forth the nature of the invention what we claim herein is- A sewing machine cabinet compri.\' ingr a table-top, supporting: means at the opposite ends of said table-top, a leaf forming.1r a

' shelf carried by said supporting means below the tabletop, a treadle mounted below and concealed by said leaf, said leaf being pivot-.illyr sustained at one end of the table and adapted to be swung to an upright or open position at- Said end of the table to expose said treadle, and a drive-wheel mounted on said leaf and adapted for operative connection with said treadle.

In testimony whereof, we have signed our naines to this specification.
